Member Function Documentation

virtual tResult CancelSignalUpdates	(	ISignalRegistry::tSignalID	nSignalID,
		ISignalListener &	oListener
	)

pure virtual

Cancels a request for signal updates.

Parameters

[in]	nSignalID	The id of the signal.
[in]	oListener	The listener.

virtual tResult RegisterSignalsListener ( ISignalsListener & oListener )

pure virtual

Registers a new listener for added and removed signals.

This will call ISignalsListener::SignalAdded for each signal currently registered.

Parameters

[in] oListener The new listener.

virtual tResult RequestSignalUpdates	(	ISignalRegistry::tSignalID	nSignalID,
		ISignalListener &	oListener
	)

pure virtual

Requests updates for a given signal.

Parameters

[in]	nSignalID	The id of the signal
[in]	oListener	The listener whose ISignalListener::SignalUpdated method will be called.

virtual tResult UnregisterSignalsListener ( ISignalsListener & oListener )

pure virtual

Unregisters a listener for added and removed signals.

Parameters

[in] oListener The listener.
